CONTROL APPARATUS, COMMUNICATION SYSTEM, CONTROL METHOD AND PROGRAM
A control device includes: a scheme determination unit configured to determine whether a packet to which an identifier of a priority is assigned is transmitted in conformity with a grant-free scheme; a time estimation unit configured to estimate a time in which a traffic volume of the packet is equal to or more than a threshold; and a transfer control unit configured to generate a control signal of a signal transfer device so that the signal transfer device transfers a packet that has arrived at the signal transfer device in the estimated time in accordance with the identifier of the priority. The scheme determination unit determines whether the repeated transmission of the packet is performed. The time estimation unit estimates a time in which the plurality of packets arrive at the signal transfer device a predetermined number of times at predetermined time intervals when it is determined that the repeated transmission of the packets is performed.
1 . A control device comprising:
a scheme determiner configured to determine whether a packet to which an identifier of a priority is assigned is transmitted in conformity with a grant-free scheme;
a time estimator configured to estimate a time in which a traffic volume of the packet is equal to or more than a threshold; and
a transfer controller configured to generate a control signal of a signal transfer device so that the signal transfer device transfers a packet that has arrived at the signal transfer device in the estimated time in accordance with the identifier of the priority.
2 . The control device according to claim 1 ,
wherein the scheme determiner determines whether the repeated transmission of the packet is performed, and
wherein the time estimator estimates a time in which the plurality of packets arrive at the signal transfer device a predetermined number of times at predetermined time intervals when it is determined that the repeated transmission of the packets is performed.
3 . A communication system comprising: a signal transfer device configured to transfer a packet: and a control device,
wherein the control device includes:
a scheme determiner determining whether the packet to which an identifier of a priority is assigned is transmitted in conformity with a grant-free scheme,
a time estimator estimating a time in which a traffic volume of the packet is equal to or more than a threshold, and
a transfer controller generating a control signal of a signal transfer device so that the signal transfer device transfers a packet that has arrived at the signal transfer device in the estimated time in accordance with the identifier of the priority.
4 . A control method executed by a control device, the control method comprising:
determining whether a packet to which an identifier of a priority is assigned is transmitted in conformity with a grant-free scheme;
estimating a time in which a traffic volume of the packet is equal to or more than a threshold; and
generating a control signal of a signal transfer device so that the signal transfer device transfers a packet that has arrived at the signal transfer device in the estimated time in accordance with the identifier of the priority.
5 . A non-transitory computer readable medium which stores a program causing a computer to function as the control device according to claim 1 .
